Epoxy coating & waterproofing in Jazan: the local context

Team note on Jazan: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Jazan sits about 7 m above sea level (SRTM open elevation data).

Jazan is about 1.9 km from the sea coast (OpenStreetMap).

Jazan sits close to the Red Sea, with the centre of the city about 7 m above sea level and roughly 1.9 km from the sea coast. That combination matters for any company planning floors, tanks or basements here. Sitting this low and this near the water means that salt-laden air and a damp ground layer are constant concerns, so a surface coating that looks sound on the day it is applied can still fail if the substrate underneath is not properly prepared and dried.

Those location facts translate directly into how we approach the work. Because the ground is close to sea level, basement waterproofing (priced at SAR 50–150 per m²) needs careful attention to water pressure from below, and we plan the membrane and drainage together rather than treating them separately. Because the coast is near, salt can creep into concrete and push moisture up through screeds, so we check moisture and salt content before epoxy coating (SAR 35–90 per m²) is laid. The same logic applies to tank internal coating (SAR 25–60 per m²), where a clean, dry, sound surface is the difference between a lasting finish and early blistering. Crack injection (SAR 40–120 per metre) is scheduled before any surface system goes on, since a hairline crack will carry water straight through a sealed face.

Business owners in this area tend to avoid a familiar set of mistakes. They rarely skip surface preparation, because they know a coating only bonds to what is clean and dry, and they do not rush the curing time between coats. They avoid choosing a single product for every zone, instead matching liquid roof waterproofing (SAR 8–25 per m²), bitumen membrane (SAR 15–35 per m²), spray foam (SAR 20–45 per m²) and XPS boards (SAR 12–30 per m²) to the job they actually do. They also avoid leaving bathrooms and wet areas to the lowest bid, since bathroom waterproofing (SAR 15–40 per m²) fails quickly when detailing at drains and joints is cut short. Planning the whole building together, rather than patching problems one by one, is what keeps these costs under control over the life of the property.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

The following signs are worth checking before they grow:

• Oil stains on a floor
• A tank that needs an easy-to-clean surface
• A warehouse floor that is wearing away

The most common causes

• Insufficient preparation.
• A damp surface that ruins adhesion — we check this before anything else.

Tools and methods, and when we use them

From the first visit to the report

1. Surface moisture reading: Epoxy is applied only when the substrate is dry enough.
2. Careful preparation: Grinding and cleaning for adhesion.
3. Layers: Primer and body coats as specified.
4. Inspection: Thickness and curing are checked.
